JACQUARID ATTACHMENT FOR LOOMS.

Applieationfiled December 21, 1923. Serial 1W0. 681,904.

To all whom it may concern:

Be it known that I, ZDENKO PODHRADSKY, a citizen of Czechoslovakia, and resident of Astoria, borough and county of Queens, city 5 and State of New York, have invented certain new and useful Improvements in Jacquard Attachments for Looms, of which the following is a specification.

My invention relates to looms and more particularly to that type of looms which include a jacquard attachment. The latter generally consists of a series of perforated cards connected together by flexible means such as cords or the like and mounted upon wires whereby said cards are supported in the loom. Heretofore the wires have been attached in position in various ways, all more or less unsatisfactory and including undesirable features. ent invention is to provide a novel arrangement and construction which enables the supporting wires to tached from the cards, at will in a simple manner and without requiring any special skill in the performance of the operations. Other more specific objects will appear from the description hereinafter. In the accompanying drawing, which 11- lustrates an example of the invention without defining its limits, Fig. 1 is a face v ew of a series of jacquard cards with the improvement applied thereto; Fig. 2 is a sectional view on the line 22 of Fig. 1; Fig. 3 is a fragmentary plan view of one of the supporting wires with the novel connecting means combined therewith, showing the same in connection with the jacquard cards and Fig. 1 is a fragmentary side View of one of said wires.

As shown, the jacquard attachment com-, prises a plurality of cards 10 located ad acent to each other and provided with the customary perforations 11, said cards belng flexibly connected with each other by means of cords 12 or way. As shown in Fig. 1 the cords 12 are threaded through suitable openings at opposite ends of the cards and at the centers thereof, so that said cords extend along opposite edges of the series of cards and along the median line thereof in the customary manner.

The supporting wires 13 are located between adjacent cards 10 as shown in Fig. 1 and extend beyond the opposite ends there- The object of the pres-- be attached to and de-' the like in the well known ofto form projections whereby said cards are supported in the 100111 in the customary manner. At those points which are in reglstry with the cords 12, the wires 13 are bent or otherwise constructed, to provide seats 14 in which the cords 12 are located. The means whereby said wires are detachably connected with the cords comprise resilient fingers 15 which are secured at one end to the wires, preferably in close proxunity to the seats 14: thereof, and which extend lengthwise of said wires over and beyond said seats as shown in Fig. 3 ,the free end of the resilient-fingers preferably extends in directionsaway from the wires as indicated at 16. As shown in the illustrated example, the resilient fingers may consist of relatively fine wires which have one end coiled about the wires 13 so as to be affixed in posltion thereon, said coiled ends being soldered to the wirr s 18 if desired to prevent any shifting of the fingers 15. As shown in the drawings and more particularly in Fig. 3, the fingers 15 all extend in the same direction lengthwise of the wires 13 with the inclined ends 16 thereof forming inner angles with the wires 13, which angles all open 1n the same direction.

Withthe described arrangement, the wires are easily connected with the cords 12 by simply introducing each wire in the space between the adjacent cards and with the cords lying in the angles formed by the in clined ends 16, after which a push in the direction of the length of the wire 13 is exerted thereon to force said fingers 15 over the cords 12 and to bring the latter into the seats 14. In this position the resiliency of the fingers 15 looks the cords 12 in the seats 14: and prevents any movement of the wires 13 relatively to said cords. When it is desired to detachthe wires, a push or pull in the relative direction is exerted thereon, whereby the cords 12 are withdrawn from the seats 14 and from beneath the fingers 15; the inherent resiliency of the latter causes said fingers to yield sufficiently to permit this disconnection of the wires 13 in a simple. and efficient manner, without any particular manual effort.

The inventionis extremely simple and reduces the operation of connecting and disconnecting the wires to the simplest form. At the same time the necessity for tying the wires 13 in position for flexing or bending the cards to enable the wires to be placed in or removed from operative position is en tirely done away with.

Various changes in the specific form shown and described may be made within the scope of the claims without departing from the spirit of my invention.

I claim 1. In a jacquard attachment for looms, the combination of a plurality of perforated cards, flexible connections tying said cards together, a supporting wire extending lengthwise between adjacent cards andresilient clamping means facing in the same direction for detachably connecting said wire with said flexible connection.

2. In a jacquard attachment for looms, the combination of a plurality of perforated cards, cords tying said cards together, a supporting wire extending between adjacent cards and resilient fingers extending lengthwise of the wire and having their free ends pointing in the same direction for detachably connecting the wire with said cords.

3. In a jacquard attachment for looms,

the combination of a plurality of perforated cards, cords connecting said cards together and extending along opposite edges and centrally thereof and a wire extending between adjacent cards and provided with seats in registry with said cords for the accommodation thereof, and a plurality of resilient fingers extending lengthwise of said wire over said seats and having their free ends projecting in the same direction whereby said cords aremaintained in said seats and said wire is detachably connected with said cords.

4. In a jacquard attachment for looms, the combination of a supporting wire provided at spaced intervals with seats resilient fingers having one end fixed to said wire in close proximity to said seats, said fingers projecting across said seats and having their other ends disconnected fromsaid Wire and pointing in the same direction to form pockets opening in said direction.

In testimony whereof I have hereunto set my hand.

ZDENKO PODHRADSKY.
